Abstract (en)
[origin: EP3151027A2] Systems and methods for estimating the actual k-space trajectory implemented when acquiring data with a magnetic resonance imaging ("MRI") system while jointly reconstructing an image from that acquired data are described. An objective function that accounts for deviations between the actual k-space trajectory and a designed k-space trajectory while also accounting for the target image is optimized. To reduce the computational burden of the optimization, a reduced model for the parameters associated with the k-space trajectory deviation and the target image can be implemented.
